UNSPSC 41181522 Properdin factor b immunological test system is a Commodity code that maps nominally to specialized immunological reagents and diagnostic test kits, but recent state and local solicitations show little activity aligned with the code's narrow technical scope. The recent opportunities tagged under this code span laboratory testing services, equipment repair and maintenance, spectrophotometry, oil analysis, landscape engineering, instrumentation support agreements, electric vehicle charger maintenance, materials testing and inspection, laboratory information management systems, meter test boards, water treatment plant construction, and fatigue testing equipment—none of which address properdin factor b immunological testing directly. The issuing bodies include county health systems (Marion County, Oregon), state health agencies (Texas Department of State Health Services), municipal utilities (City of Tampa, Lubbock Power & Light, City of Ocala Electric Utility), county transportation authorities (Broward County Transportation Department, Harris County Toll Road Authority), municipal governments (City of Orlando, City of Palm Bay), county governments (County of Santa Clara), town governments (Town of Waterford, Connecticut), and academic institutions (Lamar University, Texas A&M University System). No repeat buyers appear in the recent record.

The geographic spread covers Oregon, Texas, Florida (multiple jurisdictions), Connecticut, and California, with no concentrated pattern of activity. Representative recent opportunities include Marion County, Oregon issuing an ITB for laboratory testing services and phlebotomy for adults in custody with a response deadline of July 24, 2026; the Texas Department of State Health Services issuing an IFB for laboratory equipment repair and maintenance at the DSHS South Texas Laboratory in Harlingen with bids due July 6, 2026; and the City of Tampa issuing an RFQ for a Heck DR4900 Spectrophotometer replacement at the McKay Bay Waste to Energy facility with quotes due June 12, 2026. The code shows no meaningful recent procurement activity specifically targeting properdin factor b immunological test systems or closely related immunological testing products at the state and local level.
